所以我有一组对象.确切的类型并不重要.从中我想提取一对特定属性的所有唯一对,因此:

myObjectCollection.Select(item=>new
                                {
                                     Alpha = item.propOne,
                                     Bravo = item.propTwo
                                }
                 ).Distinct();

所以我的问题是:在这种情况下会不会使用默认对象equals(这对我来说没用,因为每个对象都是新的)或者可以告诉它做一个不同的equals(在这种情况下,Alpha和Bravo的值相等) =>相等的实例)？有没有办法实现这个结果,如果不这样做的话？

我有以下测试,有支持类,但我无法弄清楚如何验证对依赖项的调用.

{
    [Test]
    public void Test()
    {
        // Arrange
        var dependency = new Mock<IDependency>();

        var towns = new List<Town>
        {
            new Town { Name = "Lifford", County = "Donegal", Country="Ireland", Population = 1658 },
            new Town { Name = "Ballyshannon", County = "Donegal", Country="Ireland", Population = 2504 },
            new Town { Name = "Buxton", County = "Derbyshire", Country="United Kingdom", Population = 13599 },
        };

        var sut = new MyClass(dependency.Object);

        // Act
        sut.DoSomething(towns);

        // Assert
